The greatest extent I've heard of churches going to in order to gain youth attendance is having a loser service with a band ready to play some music...but having people come in to preach God to while also letting them play Halo? Are these churches luring gamers in with the prospect of Halo to merely corner them or is really just an avenue to get them to church? A few news stories have come out about the issue.
